“With strong execution and demand across our portfolio, we are pleased to report solid first quarter financial results,” said Chuck Treadway, president and chief executive officer. “These results are a testament to our team’s dedication to serving our customers and enhancing our core businesses. We are also encouraged by strengthening market conditions and the opportunities we see to capitalize on industry tailwinds ahead such as 5G and mobile network densification, indoor coverage and private networks, distributed access architectures and fiber-rich optical networks, as the economy and our industry continue to recover from the COVID-19 pandemic.”

Treadway continued, “Looking ahead, we are committed to refocusing our commercial and technology footprint around a more tightly integrated portfolio following our recent announcement to spin off our Home Networks business. We continue to take action to position CommScope for success as we execute on our CommScope NEXT strategy to optimize the business portfolio, drive above-market growth, and control costs.”

Alex Pease, executive vice president and chief financial officer, said, “During the first quarter we adapted to changing market conditions and delivered solid increases in revenue and profitability. Following the planned spin-off of our Home Networks business, we will be better able to reinvest in our core strategic markets and technologies to capitalize on the growth opportunities in our Broadband, Outdoor Wireless and Venue and Campus segments. With our optimized business portfolio, we expect to continue to build on the momentum we have seen so far this year.”

First Quarter Results and Comparison

In early April 2021, CommScope announced its plan to spin-off the Home Networks business. In this comparison discussion, reference is made to certain supplementary “Core” financial measures, which reflect the results of the Broadband Networks, Outdoor Wireless Networks and Venue and Campus Networks segments, in the aggregate. Core financial measures exclude the results of the Home Networks segment. These metrics represent the business segments as historically reported by CommScope. However, the ultimate definition of the Home Networks business that CommScope expects to spin-off may vary, and future results may differ materially.

Reconciliations of the reported GAAP results to non-GAAP adjusted results are included below.

Net sales in the first quarter of 2021 increased 1.9% year over year to $2.07 billion. Core net sales increased 10.5% year over year primarily due to higher net sales in the Broadband Networks segment.

Net loss of $(97.6) million, or $(0.55) per share, in the first quarter of 2021, decreased 39.0% compared to the prior year period's net loss of $(159.9) million, or $(0.89) per share. Non-GAAP adjusted net income for the first quarter of 2021 was $88.3 million, or $0.36 per share, versus $27.2 million, or $0.12 per share, in the first quarter of 2020.

Non-GAAP adjusted EBITDA increased 25.3% to $289.7 million in the first quarter of 2021 compared to the same period last year. Non-GAAP adjusted EBITDA improved to 14.0% of net sales in the first quarter of 2021 compared to 11.4% of net sales in the same prior year period. Core segment adjusted EBITDA increased 24.6% in the first quarter of 2021 and improved to 17.3% of net sales compared to 15.3% of net sales in the prior year period. The Company is facing supply shortages and delays that negatively affected adjusted EBITDA in the three months ended March 31, 2021, and those constraints are expected to persist at least into the second half of 2021. The COVID-19 outbreak also continued to have a mixed impact on the Company’s financial performance during the first quarter of 2021, with network strain driving increased demand for the Broadband Networks segment products, while the other segments have been negatively impacted due to the general economic slowdown.

Non-GAAP Financial Measures

CommScope management believes that presenting certain non-GAAP financial measures enhances an investor’s understanding of our financial performance. CommScope management further believes that these financial measures are useful in assessing CommScope’s operating performance from period to period by excluding certain items that we believe are not representative of our core business. CommScope management also uses certain of these financial measures for business planning purposes and in measuring CommScope’s performance relative to that of its competitors. CommScope management believes these financial measures are commonly used by investors to evaluate CommScope’s performance and that of its competitors. However, CommScope’s use of the terms non-GAAP adjusted EBITDA, segment adjusted EBITDA and segment adjusted EBITDA as a percentage of sales, Core segment adjusted EBITDA and Core segment adjusted EBITDA as a percentage of sales, non-GAAP adjusted net income, non-GAAP adjusted diluted earnings per share, non-GAAP adjusted gross profit, non-GAAP adjusted operating expense and non-GAAP adjusted free cash flow may vary from that of others in its industry. These financial measures should not be considered as alternatives to operating income (loss), net income (loss), cash flow from operations or any other performance measures derived in accordance with U.S. GAAP as measures of operating performance, operating cash flows or liquidity. A reconciliation of each of these non-GAAP measures to their most comparable GAAP measures is below.

Core Measures

CommScope believes that presenting Core financial measures enhances the investor’s understanding of the financial performance of the Company’s core businesses. Core financial measures are the aggregate of the Broadband Networks, Outdoor Wireless Networks and Venue and Campus Networks segments. They do not include the results of the Home Networks segment. The aggregate results of the Core segments and the results of the Home Networks segment represent the business segments as historically reported by CommScope and may not represent the ultimate definitions of the remaining CommScope businesses and the Home business after the previously announced planned spin-off. Future results may vary and differ materially from the presentation of the Core financial measures.
